Ameloblastic fibroma: a rare case report with 7-year follow-up

Abstract

Introduction Ameloblastic fibroma (AF) is a rare benign odontogenic tumor that usually occurs in the first two decades of life. It affects adolescents and young adults and is found in the mandible and with a higher frequency in the posterior region of this segment. There are rare case reports with a long-term follow-up.

Case Outline We report the case of a 6-year-old boy with extensive ameloblastic fibroma in the mandible. Treatment consisted of enucleation and bone curettage, with the preservation of permanent teeth adjacent to the tumor. Clinical and radiographic follow-up of the patient over a period of 7 years showed no signs of recurrence or malignant transformation.

Conclusion Patients with AF should be under follow-up for prolonged periods of time, even in cases exhibiting a low proliferation index, because of the potential for recurrence and malignant transformation of this tumor.
